D96V24DSA
3-5
RB
07:2
Relay B Activate. Activates the RBDVR output.
RBUFFER
00:0-7
Receive Data Buffer. Contains the received byte of data.
RDBF
1E:0
Receiver Data Buffer Full. Reports the status (full or not full) of the Receiver Data Buffer
(RBUFFER). (See RDBIE and RDBIA.)
RDBIA
1E:6
Receiver Data Buffer interrupt Active. Reports that the cause of an interrupt request Is
the Receiver Data Buffer (RBUFFER) full. (See RDBF and RDBIE.)
RDBIE
I E:2
Receiver Data Buffer interrupt Enable. Enables the assertion of IRQ and the setting of
the RDBIA bit when RBUFFER is full. (See RDBF and RDBIA.)
RDL
07:6
Remote Digital Loopback Request. initiates a request for the remote modem to go into
digital loop-back.
RDLE
07:7
Remote Digital Loopback Response Enable. Enables the modem to respond to the
remote modem’s digital loopback request.
PEN
06:3
Parity Enable. Enables generation/checking of parity in asynchronous parallel data
mode.
RCEQ
05:2
Receiver Compromise Equalizer Enable. Controls insertion of the receive passband
digital compromise equalizer into the receive path.
RI
0F:3
Ring Indicator. Reports detection status of a valid ringing signal.
RTDET
0E:7
Retrain Detected. Reports detection status of a retrain request sequence.
RTRN
08:1
Retrain. Controls sending of the retrain request or automatic rate change to the remote
modem.
RTS
08:0
Request to Send. Requests the transmitter to send data.
RLSD
0F:7
Received Line Signal Detector. Reports detection status of the carrier and the receipt of
valid data.
RXP
01:0
Received Parity bit. This bit is the received parity bit (or ninth data bit).
S1DET
00:5
S1 Sequence Detected. Reports detection status of the S1 sequence.
SADET
00:2
Scrambled Alternating Ones Sequence Detected. Reports detection status of the
Scrambled Alternating Ones sequence.
SCR1
00:4
Scrambled Ones Sequence Detected. Reports detection status of Scrambled Ones
sequence.
SDIS
03:2
Scrambler Disable. Disables the transmitter scrambler.
SLEEP
09:0
Sleep Mode. Controls entry Into the SLEEP mode. The modem requires a pulse on the
RESET pin to return to normal operation.
SPEED
0E:0-2
Speed Indication. Reports the data rate at the completion of a connection.
SPLIT
03:5
Extended Overspeed TX/RX Split. Limits transmit data to the basic overspeed rate.
STB
06:2
Stop Bit Number. Selects the number of stop bits in asynchronous mode.
SWRES
04:6
Software Reset. Causes the modem to reinitialize to Its power turn-on state.
